Help on exhuast!!!!

[440barracuda]

Hi, another question on exhaust....

My dad got a quote from TTI for the 3 inch, and was allitle more expensive than we thought, so we called our local exhaust man.
he says, he can take 3 inchs pipes, not mandrel bent, with a X pipe, go back to outr origional but new flowmasters, and run out to the back with the non-mandrel bent 2/14 pipes. He says that it might make better horse power, and it really cheap.
But i have another idea.....
I have seen Barracudas with the pipes coming out right before the rear wheels. Some people say there are some legal issues with this, but i have seen more than 3 cars with this setup, that is not a factory option, like on a T/A challenger.

What do you guys think about this?

[rumblefish360]

You can fab your own with an H or X pipes and over the axle kits from flow master. Use the flowmaster universal kit and cut to fit.
I did my Cuda's with it. It was easy and took a little time to do, but was worth every bit the exersize when I was done.
Mandrel bends rule, others drool. Stay away from that exhaust man. Bad news he is.
Alot also depends on the performance level of the engine as to what size you shold use.

[Dartcustom]

Its cheaper from the exhaust shop because he is using a cheaper method of bending pipe. Mandrel bending is much better because it holds the same diameter when bent as opposed to non-mandrel which gets necked down quite a bit at the bends, looks worse too. If anything it could perform worse than the TTI setup, especially if he wants to only run 2-1/4" tailpipes..yuk. Talk to a few shops before doing it. remember you get what you pay for! Hope this helps.

[440barracuda]

So i shouldnt go to that guy? what do you thinka about my idea with the pipes exiting b4 the rear wheels??/

[rumblefish360]

Oh, silly me, sorry 'bout that.
I think it's a great idea. Unless your doing it with an repro/OE T/A muffler, just stop the muffler a little short and use a 90* bent pipe and cap with chrome tip.
If it's not to much, ya might wanna extend the exiting pipe (Tip) past the rubber a tad or at least equal with it.
It's a heat and rubber reaction thing ya know.

[mtrv8n]

Neighbors will hate it, and Dodge stopped using it on the Viper because it didn't sound so good(reffering to side pipes..)

[440barracuda]

I just hope i dont get tickets for it..... i hear you can. check out this cuda on my web site, i want to do the same thing with my pipes www.mikesmusclecars.iwarp.com

[rumblefish360]

Idea option, turndowns into the street. OK, not a preety sight.
What mufflers you want to run? This is a key point here. Some are just plain quiter than the next guys.

P.S. it's a Cuda, not a chally. The purple unit at the site.

[440barracuda]

I want to run my flowmaster 2 chambers........

[kudah440]

i had side exit like a t/a or aar on mine for a while, and i hated it, and did i mention i hated it...
aweful...road junk rips it up so it cant hold chrome or even anykind of touch up to keep it from rusting...the sounds was annoying after a while, and the fumes would come right in the window at a stop light...
oh and by the way, if i remember right you have the schumaker headers like me...3 inch wouldnt really do any good for performance since your collectors are only 2.5 inch anyway...i'm happy with the 2.5inch with flowmasters then blowing straight out back on mine.
just how i see it

[440barracuda]

Well, like i said, the exuast guy cant do mandrell bending, and i am hear a 3 inch crimp would be the best....... THanks kuda that helps alot, i am glad you warned me about your expierience...

[6 packin]

At the bare minium go with 2 1/2 inch pipes. I dont see how 2 1/4 inch would save you much money. The cost diff between them should be less than a $10 spot.

[sixpackgut]

i would get a quote from TTI for 2 1/2 instead of the 3. there could be a big difference in price. plus the alum coated pipes stay nice a long time. the exhaust guys pipes will get nasty after a while. i would pay the extra for much better Q.

[440barracuda]

Well, they cant make the bends to go to the schumacher headers, so that makes more work for me

[sixpackgut]

does schumacher make any kind of extention for there header? this would seem to be a common problem for anyone that bought them. i have to tell you that i have a TTI ex on my car for years and it is still beautiful.

[littlecampbell]

I dont get all this from your exhaust shop....They are saying they cant do mandrel bends??? They must be a bunch of retards. Go to an auto parts store that carries aluminized mandrel bends of various lenghts and bends. They will be hanging from the ceiling. Then its cut and weld, cut and weld etc. No bending. My guy did it on his back with a mig welder on his back under jack stands in his garage. Oh yeah, you can haggle with these guys at the parts store. These mandrels can get very pricey.

[sixpackgut]

thats a good idea! i would still check schumacher before i did that though

[440barracuda]

Well the car is on the trailer, and ready for the exuast guy tommarrow, guess we will hold off on the TTI until the busget allows it, and when we want somthin to change on the car. We are probly going with the side exit pipes, with cut off tips, like the the car on my website www.mikesmusclecars.iwarp.com check out my 440 on the front page.......

[JVMopar]

I had side pipes on my D200. Of course it was straight pipe off of the headers into glass packs then into some 4inch chrome tips. To describe it in one word- Loud.

I got pulled over for goofing around with the local sheriff once. he was following me so I slowed down and went into the turn lane and when he passed me I pulled out again doing 30 mph (in a 60 at 2am) then he would slow down and wait for me to catch up. Then I'd mash on the gas and pull away he couldn't keep up it was kinda funny. Then I'd let off at 60. I did this 3 times and got pulled over. The first thing he said to me was "can you turn your truck off so I can hear you". I almost started laughing. No I didn't get a ticket but I deserved one for being a 18 yr old smart ass. Gosh that was 4 years ago already I'm getting old.

You can see my pipes.

[Dartcustom]

Is there only one "exhaust guy" in your town or surroundings? Surely their has to be somebody that can do mandrel bends? Oh well i tried.

[440barracuda]

No one around here can do it.... thats unless i am miss informed. and we can work a pretty good deal with this guy. Her is part of the Mopar club, so.

[Dartcustom]

Sounds like your getting a good deal, so go for it!

[440barracuda]

Yea, well my dad called me, and said we just went 2.5 non-mandrel, to a X pipe, then to the flowmaster 2 chambers, then the rest of hte way back thru the origional, but new 2 1/4 non mandrel. this isnt permanent, but for 100 bux u cant go wrong.

[fastmopars .inc]

if the 440 isn't too crazy than that exhaust system should work well on the street. an exhaust that improves flow velocity is a good one, and the way the exhaust gets smaller as the gases cool down (later on down the pipe) will help the flow to maintain velocity.
will burn the tires loose for sure!

[littlecampbell]

I'd like to see a test done on a variety of exhaust types, such as mandrel bent as opposed to not. No H or X on the mandrel bent then with them. 2", 2 1/2", 3". This done on the strip with the same vehicle. In real conditions, not a dyno. Whats the point of going to the expense of an X pipe without mandrels on a street car? Unless its just to feel good cause its there

[sam spade]

Check out this website. Its not Mopar, but some good info on exhaust system, X-pipe, and muffler testing.

[littlecampbell]

Nice article SS....All these tests are done on big blocks. This one on a 455. In Jan. 2003 issue of MM its done on a Hemi. MM says the test would be useless without a stout-performing car to try it out. So in my humble opinion on a small block such as mine the money for an H or X would be better spent elswhere. The difference would be miniscule. As far as quieting is concerned after going to 2 1/2" mandrels and Dynomax super turbos behind Hedman shorties without H or X the sound is very soft. Not at all loud even when I get on it. Its almost too quiet. A very noticable performance is also noted. Now if that pony would ever get here with my Air Gap......

[BakedMopar]

I run side pipes on my ride. 3" pipe through flowmaster 2 chambers and they are LOUD. Theres up and downs about a setup like this. One its loud, two the fumes come in at a stop, and its not really leagal. The good side about it is its easy to take off for racing or repairs plus it's loud. You should save up and do it right the next time around.

P.S. Rumble i don't know what cuda your refering to.(in the site)

[70Barracuda]

The AAR exhuast thing is bad. I had it with dynomax Rouch muffs.
It was loud and in mono!
I like my exhuast in stereo!!

[PapaBato]

Where did you go? Did you try Lewisville Muffler and Miller Muffler? I got mine done at Miller Muffler when i got my car.
